Hi, I am 38 years old and just found out I am pregnant. About a week after estimated conception, I came down with shingles on my scalp. I didn't know I was pregnant and was prescribed Valtrex at 1 gram twice a day (2 grams total a day) for 7 days. I took the medication for the 7 days and about a day after stopping it I discover I am pregnant. I am beside myself that I might have harmed this baby. I know it is pregnancy category B but I took a pretty high dose and the first trimester is so fragile! Genital herpes is a chronic, life-long viral infection. Two types of HSV can cause genital herpes: HSV-1 and HSV-2. Most cases of recurrent genital herpes are caused by HSV-2, and approximately 50 million persons in the United States are infected with this type of genital herpes . Most persons infected with HSV-2 have not had the condition diagnosed. Many such persons have mild or unrecognized infections but shed virus intermittently in the anogenital area. As a result, most genital herpes infections are transmitted by persons unaware that they have the infection or who are asymptomatic when transmission occurs. Management of genital HSV should address the chronic nature of the disease rather than focusing solely on treatment of acute episodes of genital lesions.

The antiviral drugs acyclovir, valacyclovir, and famciclovir are often prescribed to treat herpes viral infections, such as herpes simplex virus (HSV). More than one in five pregnant women have antibodies in their blood to HSV, indicating a past or present infection. Herpes antiviral medications are also used to treat herpes zoster infections, commonly known as shingles. Until now, information about the safety of these antivirals during pregnancy has been limited, according to background information in the journal article. The medications are listed as category B by the FDA.

Animal studies have failed to reveal evidence of teratogenicity for either valacyclovir (valaciclovir) or acyclovir (aciclovir; the active metabolite). No significant neonatal toxicity or fetal drug accumulation was noted in a small pharmacokinetic study (n=20) of this drug (500 mg twice daily) administered beginning at 36 weeks' gestation. Pregnancy registry data reported 1 document exposures to this drug or any formulation of its active metabolite, respectively, of which 29 and 756 exposures occurred in the first trimester. Exposure did not indicate an increased incidence of major birth defects compared with the general population in a prospective pregnancy registry; however, there is insufficient data for definitive conclusions regarding exposure during pregnancy.
